Product Description
Wet Laid Glass Fiber HVAC Filter Media is a premium non-woven filtration material manufactured through a wet-laid papermaking process using borosilicate glass microfibers with an acrylic binder system. This media delivers 100% mechanical filtration efficiency, which means performance does not rely on electrostatic charge and remains stable over time without degradation . The wet-laid production method ensures uniform fiber distribution across the entire media sheet, resulting in consistent filtration performance and excellent pleatability on standard automated pleating equipment.

Product Features
Wet Laid Glass Fiber HVAC Filter Media offers the following performance advantages:
100% Mechanical Filtration – Unlike synthetic electret media, this high stiffness air filter paper relies on fiber structure for particle capture, ensuring efficiency does not decline over time under varying humidity or temperature conditions .
High Stiffness for Superior Pleatability – The acrylic binder system provides excellent stiffness, enabling tight, consistent pleating on manual and automated equipment without media fracture. This maximizes filter surface area within a given frame size .
Graded Density Structure – Fiber density increases toward the air exit side, enabling depth loading throughout the media thickness. This mechanical filtration glass fiber media captures particles from coarse to fine in a single layer, extending service intervals.
Low Initial Resistance – Advanced fiber engineering minimizes pressure drop, contributing to reduced energy consumption in HVAC systems .
Thermal & Chemical Resistance – Stable up to 120°C with good resistance to moisture and common industrial chemicals.
Product Applications
Wet Laid Glass Fiber HVAC Filter Media is widely deployed across diverse sectors:
Commercial Building HVAC – AHU systems in office towers, shopping malls, hotels, and airports, requiring reliable particulate removal
Healthcare Facilities – Hospital ventilation, operating rooms, and isolation wards where indoor air quality is critical
Pharmaceutical Manufacturing – Cleanrooms (Class 100 to 10,000) and production areas
Electronics & Semiconductor – Clean assembly lines and chip fabrication facilities
Industrial Turbines – Gas turbine intake filtration and air compressor inlet protection
Nuclear Power – Exhaust venting systems requiring guaranteed efficiency
This ASHRAE grade glass fiber sheets material is particularly suitable for applications where consistent, non-degrading efficiency is mandatory, such as cleanroom terminal filtration and high-end air purification systems.
